2. A gaseous mixture heater comprising an elongated {iat-tened vcasingha'vingllanges on its flattened portion adapted to be secured to theadjacent anges 'of the carbureter and the intake manifold', said casinghaving oppositely disposed open ings to register with the openingsthrough said intake and said carbureter, an oriieed endvwall, tubessupported inthe orifices in said end'wall, a plurality of flange-likeringsiassembled on said tubes, an .Il

end plate adapted to support the free enzls of said. tubes, a closurecap adapted to be cured to the end wall oit' said casing, and a closure.provided with a plurality oi: split sockets adapt-ed to be secured tothe end of l the casingprovided With the orificed plante.

3. A heater for gaseous fuel, comprising tween the inlet and outletopenings and the tubes, each oi said baille plates having'a centralconical portion formed with an opening in its apex.
